A bar-graph display provides an easily interpreted graphical indicator that allows comparison with its full-scale value, but a conventional microcontroller-based design uses at least one eight-line ...

This Design Idea is a 1-dot bar graph display that provides a simple, compact, low-cost, and low-power alternative to the usual four-LED bar graph battery gauge [1]. It consists of a surface-mount ...

The LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for… ...
